Summary of The 3rd Control System Cyber-Security (CS)2/HEP Workshop

Over the last decade modern accelerator and experiment control systems have increasingly been based on commercial-off-the-shelf products (VME crates, programmable logic controllers (PLCs), supervisory control and data acquisition (SCADA) systems, etc.), on Windows or Linux PCs, and on communication infrastructures using Ethernet and TCP/IP. Despite the benefits coming with this (r)evolution, new vulnerabilities are inherited, too: Worms and viruses spread within seconds via the Ethernet cable, and attackers are becoming interested in control systems. The Stuxnet worm of 2010 against a particular Siemens PLC is a unique example for a sophisticated attack against control systems [1]. Unfortunately, control PCs cannot be patched as fast as office PCs. Even worse, vulnerability scans at CERN using standard IT tools have shown that commercial automation systems lack fundamental security precautions: Some systems crashed during the scan, others could easily be stopped or their process data being altered [2]. The 3rd (CS)2/HEP workshop [3] held the weekend before the ICALEPCS2011 conference was intended to raise awareness; exchange good practices, ideas, and implementations; discuss what works & what not as well as their pros & cons; report on security events, lessons learned & successes; and update on progresses made at HEP laboratories around the world in order to secure control systems. This presentation will give a summary of the solutions planned, deployed and the experience gained.
